Easily! 2-3 weeks recovery tops. They will just be starting to drop by then, and ready, because you'll want everyone to see them and feel them, they always do! Ed
I myself have never had breast work, however I wish you and your girls the best during your recovery!
I would be worried about going that fast. Never had a boob job, could use one but I can just imagine that they will still be sore.
I don't mean to be speaking for my wife, but last year around labor day she had a similar procedure and we went for Haloween. She was also concerned but it turned out fine, no problems and had a great time.
I would plan on 8 weeks for recovery you will need to wear support most of that time. I had mine done in January and we went in March.
I would allow 6-8 weeks for recovery. You don't want to push it. But with that said...everyone heals differently and at different rates. Good luck and I wish you the best. Best decision I ever made!
